This my third toilet roll holder design. The hanger is made from bend acrylic glass, the roll is assembled from 3d-printed parts. Spring loaded tappets secure the roll in the hanger, while making it easy to change. I added a stl for the hanger as well, if you don't have access to a cnc-router. The acrylic glass has the advantage that is can be cleaned very good, which is very useful in a bathroom.

I cut the pmma on my Sorotec BasicLine with a 4 mm single flute endmill. Making fast shallow passes and adding some liquid (water/methylated spirits) works very good, still the chips are really messy. Next step was to polish the sides. Then I milled a mold from cheap wood, where I mounted the hanger. I put it into the oven at 170 °C for a good 10 minutes. Then I put it out and bend the part with gloves.

The inner assembly was printed on a Creality Ender 3 with white PLA. I was glad that the screw worked right away. Keep in mind that you need to print the tappet twice.

As a subtle enhancement of my toilet roll holder I came up with this adaptation of the idea of changing the direction of the material like with this Woodini Stool made by Bakery Design.

Because nearly 30 mm of material is pretty hard to cut on a desktop cnc I went with gluing up three layers of 9,6 mm material. I nested the parts exactly with gaps of 3 mm to save some cutting.
